Historically, the concept of a function has been developed into the concept of today's abstract and logical functions by mathematical necessity, starting with an intuitive idea to observe the movement and changes of objects, and functioning to understand various real situations or to integrate the fields of mathematics. In this process, as various aspects of functional thinking are implied, abstracted, and formalized, it is difficult for students today to understand the notion of functions.
The study aims to analyze the mathematical principles of ladder games, examine the parts of function units related to ladder games in the 2015 revised secondary curriculum, and present teaching and learning methods for functions.
In the 1st session, the ladder game was mathematically formulated to express it as a permutation, the existence of a ladder game corresponding to a given permutation, how to draw a ladder game for a given permutation, and the nature of ladder game was analyzed.
In the 2nd session, using the ladder game, a teaching and learning plan of the function is presented. The meaning of one-to-one functions, constant functions, composite functions, and inverse functions is easily and interestingly introduced through specific examples of ladder games.
